BURNER.

To all 'whom it may concern.'

Be it known that I, ANDREW 'I`. STILL, ay citizen of the United States,residing at Kirksville, in the county of Adair and State of Missouri,have invented certain new and useful Improvements in Burners, of whichthe following is a specification.

My invention relates to a burner, and particularly to a type of burnerin which means is employed to cause fuel in combustion to move inconverging paths which intercept each other, and the primary object ofmy invention is the provision of devices by the use of which to utilizea greater percentage of the heat units in a fuel substance.

With the above and other objects in view, my invention consists in thediscovery disclosed herein and in the mechanism to practice theinvention, and in the novel features and in the novel combination andarrangement of parts hereinafter more specifically described, and allparticularly pointed out in the claims hereunto appended.

I attain these objects by the mechanism illustrated in the accompanyingdrawings which are made a part of this specification,

' and in whichv- Figure 1 is an elevation, partly in central verticalsection, and partly broken away. Fig. 2 is a section through the mixinghead.

A preferred embodiment of my invention is described as follows:

For the purpose of obtaining a greater proportion of the molecularenergy from a liquid or gaseous hydrocarbon, I have constructed what istermed a deflecting element 3 comprising a circular tapering portion 4with the forward end 5 open, and a rear iange 6 to secure the element tothe burner. The defiector may be of any suitable or desired contourlines. Preferably it consists of a hollow frustum of a cone open at bothends and disposed in advance of the burner and is adapted to causeburning gases to move in converging paths which intercept each other ata point in advance of the deflector. The furnace member 7 and the domemember 8 of the burner each has an external annular ange 9 through whichare inserted bolts 10 to hold the members together and to secure thedeflecting element in position. The space 1l between the members is anexpansion chamber. The short Specication of Letters Patent.

Patented Apr. 26, 1910. serial No. 441,941.

lengths of pipe 12 serve to maintain the fiange 6 and the ange 9 apredetermined distance apart to provide vfluid passages 13. The annularseries of jet apertures 14 afford fluid fuel outlets from the burner.The upright tubular boiler 15 rests upon the foundation 16 whichincloses the firebox 17 in which the burner is disposed. The tank 18holds a liquid hydrocarbon which is adapted to carburet steam which ispassed from the boiler through pipe 22 into and through pipe 19 into thetank 18, and through pipe 20 to the spraying or mixing head 21, andthence through pipe 26 to the burner space 11 and through the jetapertures 14.

Air is mixed with the carbureted steam by -the employment of theprinciple of the Bunsen burner through the air pipes 30. The force withwhich the carbureted vapor passes out of the lower end of the pipe 26creates a partial vacuum in the tube 27 and causes an inrushing of airthrough the pipes 30.

In operating when the Huid fuel under pressure arrives at the apex ofthe furnace member it will then be in the presence of intense heat andwill be expanded and will pass through the burner with force.Immediately upon its exit through the jet apertures combustion will takeplace and the direction of the lines of energy will be changed by theangle of the adjacent surface of the deiieeting element and the lines ofenergy will cross at a point in advance of the deiecting element. Thepassage 13 will permit a circulation therethrough.

It will readily appear that my invention has a wide range ofapplication, and is not limited to any one class of burners, but may beapplied to any burner with which it is desired to increase the heat froma given amount of fuel by causing the flame or lines of combustion tomove in converging paths which intercept each other.

Having` thus fully described my invention, what I claim as new, anddesire to secure by Letters-Patent, is,

1. In a burner, a deflecting element comprising a hollow frust-uin of acone open at both ends and disposed in advance of the burner and adaptedto cause burning gases to move in converging paths which intercept eachother at a point in advance of the deflectng element.

2. The combination with a burner and means to supply fuel under pressurethereto, of a deeetor comprising a hollow frustum of a cone open at bothends and dsposed n advance of the burner and adapted to cause burninggases to move in converging paths which intercept each other in advanceof the defleetor. 10

In testimony whereof, I aflx my signature in the presence of twowitnesses.
